Measurement, calibration and probe storage apparatus for measuring pH of fluids and slurries
First Claim
1. A measurement, calibration and probe storage apparatus for use in connection with the protection of oil and gas comprising:
- a) a rigid, protective, mountable, enclosure having a conduit means routed therethrough for the conveyance of at least one of a fluid, a slurry and mixture thereof;
b) a cylindrical flow chamber being configured to accommodate a removable probe sensor means therein and a removable dust cap thereon, the flow chamber being in fluid communication with the conduit;
c) at least one removable dip probe sensor means for measuring a preselected attribute of said at least one of a fluid, a slurry, and mixture thereof, in which the probe sensor is immersed;
d) an electronic processor means in electrical communication with the probe sensor for calculating and rendering a value of the attribute being measured;
e) a cylindrical probe sensor storage and calibration chamber being proximal to the flow chamber, adapted to accommodate the removable probe sensor therein and a removable dust cap thereon, the storage and calibration chamber further having a drain tube and an overfill tube, both being in fluid communication with the storage and calibration chamber, the drain tube being selectively controlled by a multi-position control valve means;
f) a dust cap being configured to be accommodated by the flow chamber and the storage and calibration chamber; and
g) a control valve means for selectively controlling the filling of the storage and calibration chamber from at least one calibration fluid reservoir, and for the draining of the calibration chamber.

Abstract
A measurement/calibration/probe storage apparatus particularly suitable for measuring pH of fluids and slurries used in the treatment of oil and gas wells. The apparatus includes an enclosure having a conduit for the conveyance of a fluid or slurry therein, a flow chamber being in fluid communication with the conduit, a probe sensor for measuring a preselected attribute of a fluid, or slurry, residing within, or, passing through the flow chamber. The apparatus further includes an electronic processor in electrical communication with the probe sensor for calculating and providing a display of the attribute being measured and a calibration chamber being configured to receive the probe sensor. At least one calibration fluid container being in fluid communication with the calibration chamber is also provided. A control valve is provided for controlling the flow of fluid from each calibration fluid container into the calibration chamber and for controlling the draining of the calibration chamber.

10. A pH measurement, calibration and probe storage apparatus for use in connection with the production of oil and gas comprising:
-
a) a protective, mountable, steel rectangular enclosure having mounting tabs and a front access panel and having a conduit means routed therethrough for the conveyance of at least one of a fluid, a slurry, and mixture thereof; b) a cylindrical flow chamber being configured to accommodate a removable probe sensor means therein and a removable dust cap thereon, the flow chamber being in fluid communication with the conduit; c) a shut-off valve being located in the conduit means upstream of the flow chamber; d) at least one removable dip probe sensor means for measuring the pH of at least one of a fluid, a slurry, and mixture thereof, in which the probe sensor is immersed, and the probe sensor means being provided with a means for shielding the probe sensor from particles and abrasives that may be present within the at least one of a fluid, a slurry, and mixture thereof, being measured; e) an electronic processor means in electrical communication with the probe sensor for calculating and rendering a value of the attribute being measured and the electrical processing means including an output means for recording measurements and including an input connection for connecting auxiliary power means; f) a cylindrical probe sensor storage and calibration chamber being adapted to accommodate the removable probe sensor therein and a removable dust cap thereon, the storage and calibration chamber further having a drain tube and an overfill tube, both being in fluid communication with the storage and calibration chamber, the drain tube being selectively controlled by a multi-position control valve means; g) a dust cap being configured to be accommodated by the flow chamber and the storage and calibration chamber; and h) a multi-position control valve means for selectively controlling the filling of the storage and calibration chamber from at least two calibration fluid reservoirs, and for the draining of the calibration chamber. - View Dependent Claims (11, 12)
